An area on board a ship or station which allows access to or from space. Airlocks generally have a pressurized door leading into the vehicle, and another leading to the exterior. Shuttle bays can be considered to be giant airlocks.9

A form of matter in which the charge of the subatomic particles is reversed. Matter and antimatter mutually annihilate one another on contact, releasing large amounts of energy, and this process is used to power Federation Starships.22

Element of the warp drive system of an NX class starship. In an alternate timeline Captain Archer devised an improvement to the antimatter inducers which allowed Enterprise to travel farther on less fuel.27

Element of the warp reactor of an NX class starship. Disconnecting the antimatter junction from the primary antimatter feed would prevent an antimatter cascade from jumping between the warp manifold and the reactor core itself.29

Element of the warp drive of an NX class starship. The linings of the relays were coated with a platinum-cobalt alloy. Stripping the coating from 200 relays was sufficient to yield half a litre of pure platinum.31

A Borg term describing the incorporation of other life forms into their collective. This is achieved by a combination of injecting the subject with nanoprobes and the surgical implantation of machine elements. A basic assimilation is effective within seconds.38

An area on board USS Voyager in which advanced long range sensors determine the location of many millions of stars simultaneously, allowing a great increase in mapping accuracy over conventional systems.41

Element of the warp drive of an NX class starship. The auto stabilisers kept the warp field balanced; their function could be disrupted if the ship was operating in close proximity to other warp drive vessels.47

A procedure built into Federation Starships which allows them to destroy themselves in order to prevent capture.50Some autodestruct modes detonate explosive devices within the ship,51while others bring all of the antimatter fuel into contact with matter simultaneously. This mode is more than sufficient to completely vaporize the largest vessels.52Most vessels require both the Captain and one or more senior officers to agree in order to engage the autodestruct feature.51
